IILK-BQTTLE CLOSURE.

Application filed September 20, 1924. Serial No. 738,789.

York, and State of New York, have invented certain new and useful Improvements in Milk-Bottle Closures, of which the following is a specification.

This invention relates to bottle closures and in particular to a type adapted for use with milk bottles which will render the latter air-tight.

A particular object of the invention is to provide an elastic or the like closure for milk bottles which will render the same airtight so that the milk will not absorb all the food odors in a refrigerator as is the case with bottles having the cardboard or other nonairproof closure.

A further object is to provide a closure which can be rolled on and off the neck of the bottle, so that it may be placed in position with a minimum of time and effort and which when in place, will effectively seal the bottle and preserve the contents thereof.

A further object is to provide a rubber or like ex andable closure which can be molded, an sold in quantities thereby reducingthe cost of the article to the consumer.

Referring to the drawing wherein I have shown a preferred embodiment of my invention:

Figure 1 is a view in elevation of the upper portion of a milk or other bottle having 3 applied thereto my improved closure,

Figure 2 is an enlarged view in cross section through the upper portion of the bottle and closure showing the shapeof the closure; and

Fi showing the closure ro led up and ready to be lifted off the top of the bottle.

Referring to the drawing in detail 5 indicates the upper portion of a bottle of the 45 usual ty e having applied thereto my improved c osure 6. This closure is preferably made of rubber and is molded to provide a relatively thicktop portion 7 in the edge of which is formed a groove 8, the extended re 3 is an enlarged view in elevation flange portion 9 of the closure being made thin as at 10and having formed around its lower edge the outwardly protruding bead 11. The lower thin portion 10 is molded so that it will securely hug the neck of the bottle and render it air tight.

The top of the closure is provided with an integrally formed interior guide member.

12 which is of course molded in the closure. This guide member serves two purposes. It provides for the placing of the closure in proper position on top of the bottle preparatory to rolling the side of said closure down over the neck of the bottle and further, it closes the mouth of the bottle and prevents the contents thereof from getting out.

When the closure is in position as shown in Figure 2, and it is to be removed, it is simply necessa-r to place the thumbs on the top of the c osure and with the fingers roll the head 11 upwardly until it enters the groove 8 where it will be held. At this time the closure can be readily lifted ofi the top of the bottle.

'When it is desired to apply the closure the guide member 12 is placed in the top of the bottle and the bead 11 is rolled down over the neck of the bottle.

It will be seen therefor that I have provided a bottle closure which can be quickly applied or removed and which will render the bottle absolutely air proof thereby preventing the contents from becoming impregnated with the odors of surrounding food when the bottle is in a refrigerator, and also prevents contact of air with the milk to cause the same to sour.

Having described my invention what I claim is A bottle closure having a flange portion the lower part of which is relatively thinner than the upper art, the upper part being formed to provi e a groove, the lower ed e of the flange being, beaded whereby t e flange can be rolled off the neck of the bottle, the rolled portion fitting into and being held in said groove.
